Great to be in the USA I suppose.

The new trucks are quite a bit lighter. I feel like I've seen this same thread pop up a bunch of times where people move from a previous gen F150 into a 2015+ and say its unstable and I feel like some of that has to be the weight difference.

What was the gearing, cab size, and bed size of your 2007 truck?

I thought that too. But I think it's a suspension issue. Or a weight distribution issue. Maybe the CG is different in the newer rigs that gives them a less stable feel.

Or the crappy OEM shocks. Dozens of threads about bad shocks.

That would definitely contribute. The front of the 5.0L is way heavier than the back. You feel it on humps in the road. The back bucks up and the front takes heavy dips.

Oh yeah, the factory shocks certainly suck. I dont tow much but I do have air bags for payload and you can tell that even with the air bags pumped up and the truck leveled, the shocks dont handle loads. It still shimmys and squirms.

I and many others have this same issue while towing trailers that we have towed with previous trucks or friends trucks with no problems. Proper set-up may help, but I firmly believe that the issue is with the electronic steering being too light/sensitive. I saw mention of a TSB for steering does anyone have any more information on that? I have been towing various trailers for decades with all types of trucks and have never experienced the squirrely feeling I get when towing with this truck. Even towing my 18' boat with very little tongue weight can cause this unsteady feeling (although to a lesser degree), which just reinforces my belief that this has little to do with tongue weight, being over payload, or an improperly set up WDH.

There are so many different factors that affect towing feel. Certainly steering, trailer balance and tire inflation are three large ones. But also vehicle weight, tire selection, wheelbase, vehicle vertical center of gravity, hitch set up and vehicle loading are important too. I would think it difficult to make an unbiased comparison given how many variables there are to control.

Yes there is a steering update they can perform. It's actually not a tsb, it's a ssm 45685.. I think it stands for special service message or something. I hated to have to waltz in to the dealer and hand them printed out copies of what my truck needed, but they performed the update and I could tell a nice difference..

Sorry the pic is sideways

Does anyone know if this is for 15's or for all model years?
